To all whom z't may concern.-

Be it known that we, Cnsama BARBIERI, a subject of the King of Italy, and JOHN S. TnoMPsoN, a citizen of the United States, both residing at Chica 0, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Printing-Machines, of which the following is a description.

Our invention relates to that class of de vices known as printing presses and the object of our invention is to provide a simple, convenient, ra id and durable device of the kind describe especially adapted for printing letters orcirculars, a port-ion of which it is desired to maintain as a constant or I fixed statement or form, while certain other portions are regularly changed, for example, in a circular letter the body portion of which remains the same for a large number of letters while the salutation or the name and address of the art for whom each letter is intended shou d obviously be changed for each impression.

To this end our invention consists in the novel construction, arrangement and com bination of parts herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings wherein like or similar reference characters indicate like or corresponding parts.

In the drawings for the purpose of illustration we have shown our improvement arranged for printing form letters or circulars together with the cnvclops for mailing the s'amc. As shown 1 is the main frame or housing of our device upon which a cylindrival rolatabl bed 2 is mounted. The bed 2 40 upon t e sha may be of any desired form or construction adapted to receive a type form upon its surface and to maintain the same in proper position to produce the desired impression when in o eration.

In the orm shown the bed consists of a substantially regular cylinder having the portion upon which the form rests suitably nished to provide the necessary bearing surface for the form, a shaft 3 extends through the bed or cylinder 2 at its axis and is rigidly secured at both ends to suitable projections u on the frame or housing 1 with suitable %earings provided in the end walls of the cylinder or bed to loosely engage the shaft 3 and permit the free rotary movement of the bed upon the shaft.

Obviously in printing circular letters the body portion of the letter remains the same while the address and salutation must usually be changed for each letter, and for this reason in the preferred construction the type form is arranged in sections, the main or body portion 4 of the form is referably constructed of movable type in t e usual or any desired manner, although it is obvious that thisportion may consist wholly or in part of half tones, engravings, stereotypes or the like. The part 5 comprising the name of the party for whom the letter 15 intended with the address and salutation is separately mounted and adapted to be changed at each 0 erative movement of the bed. Any suita le means maybe provided for changing this portion of the form.

outer end of the slide 6 of suitable form to receive a plate or carrier 9 upon which a suitable block or the several type comprising this portion of theform is mounted. In the preferred construction the head 8 is curved .to corres 0nd with the arc of the bed 2 and a suitable ip or projection 10 is provided at each end of the head. The carrier 9 is provided with projecting resilient portions 11 adapted to engage the lips 10 to resiliently maintain the carrier in position upon the head. The several parts are so formed that if the head is forced outward slight] and the carrier then held stationary whi e the bed is moved as in operation, the head will be withdrawn from the carrier. In the construction shown a pair of magazines 12 and 14 are provided at the periphery of the bed?! slightly beyond the path of the head 8 radi= ally. A pair of resilient jaws 15 are provided at tile end of the magazine 12 adjacent the bed, so formed that when a carrier is positioned within the magazine the ends of the carrier will rest upon a projecting part 16 of each jaw and hold the carrier in position. Suitable means are rovided for moving the slide 6 together wit the head 8 and carrier 9 outward when the carrier is in proper relation to the ma azine 12 whereby the carrier on the head is orced upward between the jaws 15 into suitable position to be engaged and supported thereby. When thus positioned a catch 17 which is pivotally mounted upon the walls of the magazine as at 18 engages the forward or advance edge of the carrier and prevents its further move ment with the head thereb disengaging the carrier from the head and leaving the carrier in the magazine while the empty head passes onward into the lower end of the magazine 14. The magazine 14 is also provided with a pair of resilient jaws 20 with projections adapted to engage the ends of a carrier 9 to maintain the same in the path of the head 8 after depositing acarrier in the magazine 12. A movable stop 21 is also pro vided to engage the forward or advance edge of the lower carrier in the magazine 14 to maintain the carrier in position while the head 8 is moving into full engagement therewith. In the form shown the stop 21 is pivotally mounted upon the magazine as at 22 w th a spring 23 arranged to engage and re- SlllBDi-lX maintain the stop in engaging position. cam face 24 is provided at each end of the stop 21 adapted to cooperate with a suitable cam 25 upon the head so that when the head is fully engaged with the carrier the cam 25 will operate to raise the stop 21 and release the carrier ermittin the same to move forward with t e head in printing position.

.In the preferred construction a limit stop 28 is provided upon the head 8' ada ted to engage the rear edge or other suita' e portion of the carrier 9 -to accurately locate the carrier in position upon the head. The limit stop 28 is movable upon the slide 6 and head 8 and slightly before the carrier enga es the catch 17 the imit stop 28 is retracted mit the disengagement of the head from the carrier. Any suitable means may be prov1 ded for controlling the position of .the slide 6 and limit stop 28. In the form shown a cam 26 is rigidly secured to the shaft 3 adacent the slide 6 and a suitably formed roller.or other convenient means 27 is attached to the slide adapted to 006 erate with the face of the cam to periodical y force the slide outward against the action of the springs 7-7.

A cam 29 is also mounted u on the shaft 3 and cooperates with a suita le roller28 or equivalent means upon the inner' end of the limit sto 28 to periodically force the stop outwar and a spring 29" or other reperlot

aa aaem a silient means extends from the stop to the slide 6 adapted to normally maintain the stop at the inner limit of its movement.

Suitable means are also provided for attaching the type to the bed 2, obviously suitably curved stereotypes, etchings or the like may be provided and attached to the bed in any suitable manner. In the form shown however, each part of the form is composed of a plurality of individual type mounted between guards 0r rails extending longitudinally of the bed with the foot end of each type preferably resting against the bed or upon a suitable backing material attached to the bed. In the preferred form shown the body portion 4 of the form comprises a curved late 30 adapted to snugly fit the exterior o the bed and provided with a plurality of bars 31 extending longitudinally of the bed and rigidly secured to the plate. Each bar is provided with an enlarged portion 32 alon its outer edge. The distance between the Hit sides of the several bars 31 is suitable to receive a row of type 33 between them. A groove 34 is provided in each edge of each type of suitable size and so positioned as to receive the enlarged edge 32 of the bars and rigidly retain each type in position with its foot firmly pressed against the plate 30. A resilient pad or block 35 is provided of suitable size to tightly fit between the bars at the end of each row of type to prevent lateral movement of the type and retain the line within proper boundaries. The plate 30 may be secured to the bed 2 in any desired manner. As shown the edges of the plate 30 are beveled outward toward the bed. As shown in Fig. 15 a suitable projection 53' is provided at each edge of the bed. the face or inner edge of each projection being formed to fit the edge of the plate so that when the plate is forced against the projection it will be firmly pressed against the bed. The space between the projections is suflicient to permit the convenient removal of the plate and a suitably formed filler 30 is provided to fill the space between the projection and the plate. Suitable set-screws 30 or other convenient means are provided to force the filler against the plate to firmly clamp the plate in position. The carrier 9 is preferably composed of steel, brass or other suitable material and is preferably formed with longitudinal channels 38 adapted to receive the type and engage the grooves 34 in the sides of the type and hold the type in position upon the carrier 9 so that the foot of each type will press against the outer face of the head thereby producing an abso: lutely rigid base for the entire form.

Any suitable means may be provided for presenting the paper to the form. As shown an impression cylinder 40 having a suitable Impression surface 41 is rotatably mounted npon the frame 1 in bearings 42. The bearlugs 42 are each preferably positioned in a slot 43 or other convenient means for permitting their adjustment laterally and a screw 44 or similar adjusting means is provided adapted to engage each bearing 42 to adjust its position and rigidly maintain the same in any desired relation to the bed 2 so that when a sheet of paper is positioned upon the impression surface it will be brought into contact with the form with suitable pressure. The impression cylinder may be of the usual or any preferred form preferably having an opening 45 in one side with suitable rods 46 adjacent the edges of the impression surface for attaching the ends of the draw sheet 47 to hold the same in position upon the impression surface in substantially the usual manner. Suitable means are also provided for attaching the paper to the impression cylinder during the printing operation. In the form shown a shaft 48 is mounted in suitable bearings upon the end walls of the cylinder with any desired number of resilient clips or grippers 49 rigidly attached thereto adapted to cooperate with the inclined face 50 of the edge of the impression surface to hold a sheet of paper between them. In the form shown a collar 52 is rigidly secured to one end of the shaft 48 outside the cylinder. A rod 53 is pivotally attached to the collar 52 at one end, its opposite end is loosely engaged in a pivotally mounted bearing 54 and a spring 55 extends from the bearing 54 to a suitable collar or projection upon the rod. A pair of cam faces 56 and 57 are also provided on the collar 52 and a pair of rigid arms 58 and 59 are secured to some suitable portion of the frame each having a part extending into position to engage one of said cam faces and partially rotate said shaft. The several parts are so constructed and arranged that if the impression cylinder is rotated in the direction indicated in Fig. 21 when it arrives at the point where it is desired to engage the paper the arm 58 will engage the cam face 56 compressing the spring 55 and rotating the shaft 48 sufli clently tocarry the pivotal connection between the rod 53 and collar 52 past the center line between the shaft 48 and bearing 54 after which the spring continues the movement of the shaft to cause the grippers to engage the paper and firmly hold the same until the cylinder arrives at the point Where it is desired to release the paper. At this point the projection upon the arm 5!) engages the cam face 57 compressing the spring 55 again and rotating the shaft 48 in the opposite direction. thus removing the grippers from their engagement of the paper.

Any suitable means may be provided to rotate the impression cylinder at a speed corresponding to the movement of the form. As shown a gear 61 is rigidly attached to a central projection 63 upon one end of the bed and a suitable gear (32 is attached to the impression cylinder and arranged to mesh with the gear 61 so that a movement of the bed 2 will produce a corresponding movement of the impression cylinder 40.

Suitable means are also provided for automatically feeding the sheets of paper one by one to the impression cylinder. In the form shown a stationary bed or table 65 is mounted upon the frame 1 in position to support the paper above the impression cylinder. A eceptacl 6 is provided upon the table 65 of suitable size to receive the paper and hold it in a neat even pile. The end of the receptacle adjacent the impression cylinder 40 projects beyond the table ()5 and a movable slide 67 is provided adapted to extend transversely across the opening thus left in the bottom of the receptacle (ill. The slide 67 may be mounted in any suitable manner to move transversely of the opening. As shown the slide is provided at each end with an arm (58 formed upon a plate (it-5 positioned immediately below the table and provided with suitable guides or ribs 68 formed to fit in suitable ways or grooves 69 formed in a member 69 rigidly secured to the frame 1. The plate 68 is provided with a rack section 70 extending substantially parallel to the guides 68 and adapted t cooperate with a pinion 71 rigidly mounted upon the shaft 72 which is in turn rotatably mounted in suitable hearings in the frame 1 so that by rotating the shaft 72 the slide 67 may be moved to and from the edge of the table 65 below the opening in the receptacle 66. A roller'73 is mounted between the arms 68 in close proximity to the inner edge of the slide 67 and a pinion 74 is rigidly attached to the roller and arranged to mesh with a section of rack 75 rigidly mounted upon the side wall of the receptacle 66. The several parts are so proportioned and arranged that the upper surface of the roller travels in the opposite direction and substantially at the same speed as the plate 67, so that the surface of the roller in contact with the paper has no motion longitudinally of the paper, but as the roller rotates its surface merely moves vertically to and from the paper.

Any suitable means may be provided for temporarily attaching the single bottom sheet of paper in the receptacle ()6 to the surface of the roller 7?) so that as the plate 67 moves inward to close the opening in the bottom of the receptacle a single sheet will be separated from those in the receptacle and its margin carried into position to be engaged by the grippers 49 upon the impression cylinder 40. In the form shown the roller 73 is tubular (see Figs. 4 to 17 inelusive) with one end closed and a series of lateral openings 77 arranged ubstantially in line longitudinally of the roller, are provided in the wall of the roller. A suction pipe 78 is attached to the opposite end of the roller and connected to a cylinder 79 having i uitable piston positioned therein and arranged to operate as a pump. Each suction stroke of the piston exhausts the air from the roller thus tending to produce a current of air into the openings 77 which are temporarily covered by the paper. The lower sheet in the receptacle 66 is thereby firmly attached to the surface of the roller and firmly held in position while the roller is rotated into the position shown in Fig. 17.

At this point the suction stroke of the piston 7 is completed and it starts on its return movement thereby tending to expel any air which i may have entered the roller through the openings 77 and releasing the paper from the roller. In the preferred form shown a resilient scraper 80 is attached to the plate 69' and adapted to engage the edge of the sheet to free it from the roller. A guide 81 is also preferably mounted upon the Slldt' ()7 arranged to partially control the position of the sheet when released from the roller. The pa er when thus released and detached from tie roller springs out substantially as shown in Fig. 19 into position to be engaged by the grippers. When in this position the remainder of the paper in the receptacle 66 is supported at both ends thus preventing any disarrangement of the lower sheets as the sheet engaged by the grippers is drawn out from the pile in the receptacle by the movement of the impression cylinder.

Any suitable means may be provided for rotating the shaft 72. In the form shown a pinion 85 is rigidly mounted at the end of the shaft and an arm 86 is pivotally mounted upon the side of the receptacle as at 87, the free end of the arm having a segment, formed thereon adapted to cooperate with the pinion 85 so that an oscillation of the arm 86 will rotate the mnion. The arm 86 may be oscillated in any suitable manner. As shown a rod 88 is pivotally attached to the arm 86 as at 89 with its opposite end attached to an arm 9021s at 91. A central portion of the rod 88 is curved or provided with a lot 93 adapted to loosely receive the projection 63 upon the bed 2. A roller tud 94 or other suitable means is also provided upon the rod 88 adapted to coiiperate with a cam 95 upon the projection 63 so that as the bed 2 is rotated, the rod 88 will be moved longitudinally and actuate the arm 86 and connected mechanism to periodically deliver a single sheet of paper to the impression cylinder.

Any suitable means may be provided to ink the form upon the bed 2. As shown the side of the form adjacent the impression cylinder is partially inclosed by a pair of stationary guards 100 and 101 attached to the frame 1 and each extending across the entireface of the form longitudinally of the bed. sufficient space is left however, between the adjacent ends of the guards to permit contact between the impression cylinder and the form. A bell-crank 102103 is pivotally mounted at each end of the bed 2 upon the shaft 3 with the arms of each bell-crank extending radially of the bed. A pair of rollers or equivalent means 101-105 extend between the free ends of the bellcranks each substantially parallel to the shaft 3. A bolt 106 is also provided to connect the free ends of the bell-cranks substantially parallel to the adjacent roller for accurately controlling the distance between the bell-cranks to insure the proper operation of the rollers.

Suitable means maintaining the several parallel with the shaft venting twisting or rotation of the bellcranks independently of each other. In the form shown, a shaft 107 is mounted in suitable bearings in the end walls of the bed 2 substantially parallel to the shaft 3 and a suitable pinion 108 is rigidly mounted upon each end of the shaft 107 and each arranged to mesh with a gear 109 secured to the respective bell-cranks so that a rotary moveare also provided for parts accurately ment of either bell-crank will rotate thc shaft 107 and thereby produce an exactly corresponding movement of the bell-crank at the opposite end of the bed. The rollers 101-105 are preferably provided with suit: able means to prevent their free rotation and an inking ribbon 110 is mounted upon the rollers with a part extending between the rollers and supported by the guards 100101. The portion of the ribbon extending between the guards is obviouslv normally out of contact with the type exce it when the inipression cylinder forces t e ribbon inward against the form.

Any suitable means may be provided for oscillating the bell-cranks 102-103 upon the shaft 3 -to move the inking ribbon with the form during the printing operation and to return the parts to starting position before the next succeeding impression.

In the form shown a pinion 121 is rigidly secured to one of the bell-cranks concentric with the shaft 3 and a segment 122 IS pivotally mounted upon a pin 123 rigidly secured to the frame 1 in position to mesh with the pinion 121. A suitable roller 124 is mounted upon the segment 122 in position to engage the groove and coiiperate with a cam 125 rigidly attached to the end of the bed '2. Obviously as the bed rotates the segment will be oscillated by the cam which in turn will oscillate the bell-crank, the several parts being so constructed that the 3. that is, for premovement of the ribbon extending between the rolls will accurately correspond with the movement of the face of the type comprising the form.

Any suitable means may be provided for partially rotating the ribbon rollers periodically. In the form shown, a ratchet wheel 111 is provided at the end of the rollers 101 and 105 respectively and a pawl 112 is provided to engage either of said ratchet wheels to rotate the rollers in the desired direction. As shown. an arm 114 is pivotally mounted at one end as at 115 upon the frame 1 and provided with a slot 116 intermediate its ends. The double ended pawl 112 is pivotally mounted at the free end of the arm 11-1 and provided with two projecting fingers 117 at its back. The freeends of the fingers 117 are each attached to the arm 114 by a spring 118 or other suitable resilient means adapted to normally maintain the pawl 112 in suitable position so that when the arm 114 is in the position shown in Fig. -l. the lower end of the pawl 112 will engage the ratchet 111 attached to the roller 105 and rotate the ratchet one notch or tooth for each oscillation of the rollers and when the arm is raised slightly the upper end of the pawl will engage the ratchet attached to the roller 10% and rotate the ratchet one notch in the opposite direction for each oscillation of the rollers.

As shown, a crank 119 is rotatably mounted upon the frame 1 with a handle at the outside of the frame for turning the same and a wrist pin 120 positioned in the slot 116 so that by turning the crank 119 the pawl may be positioned to engage the. ratchet wheel attached to the roller 104 or 105 as desired.

\Vhere it is desired to provide an envelop for each letter. an envelop impression cylinder 130 may be provided, having an impression surface 131. The impression cylinder 130 is mounted upon a shaft 132 which is in turn rotatably mounted in movable hearings 133 arranged in a slot 134 or other convenient means for permitting the ad- '2. v A screw 135 or other convenientmeans is provided for accurately adjusting each bearing in the slot and for maintaining them in their adjusted position. The impression surface 131 is provided with a draw sheet 136 and a pair of resilient grippers 137 mounted upon a shaft 138 adapted impression to cooperate with one edge of the and hold it surface 131 to engage the envelop in position upon the cylinder.

In the form shown the shaft 138 extends longitudinally of the impression cylinder and is supported in suitable bearings in each end wall of the cylinder. A collar 138' is rigidly secured to one end of the shaft outside the end wall of the cylinder. One

JHSUHPIH of the cylinder to or from the bed i The several parts are so constructed end of a rod 138 is pivotally attached to the collar 138'. Its opposite end is loosely engaged in a movable bearing 13B and a spring 138 extends from the bearing to a suitable stop or enlargement upon the rod.

A pair of cam-faces 138 and 138" are also provided upon the collar 13S and a pair of rigid arms 132' and 132 are rigidly secured tosome suitable portion of the frame to maintain the arms in position. 1 A part 132 is provided upon the free end of each arm adaptedto alternately engage the cam-faces 138 and 138 to partially rotate the shaft. and arranged that with the impression cylinder rotatin in the direction indicated in Fig. 22 of t e drawings, when it arrives at the point where it is desired to engage the paper, the part 132 upon the arm 132' will engage the cam face 138 and rotate the shaft 138 suificiently to carry the pivotal connection between the rod and collar past the center line between the shaft 138 and bearing 138 after which the spring will continue the movement of the shaft and hold the grippers in an engaging position until the cylinder reaches a point where it is desired to release the paper. At this point the part 132 upon the:arm 132 engages the camface 138 rotating the shaft 138 in the opposite direction and retracting the grippers from the paper.

A gear 139 is rigidly secured to the shaft 132 and arranged to mesh with the gear 61 so that the impression surface 131 will travel at exactly the same speed as the face of the type upon the bed 2.

Any suitable means may be provided for automatically feeding the envelops into position to be engaged by the grippers 137. In the form shown a receptacle 140 is provided of suitable size to receive the envelops each lying in a horizontal position. A stop 141 extends across the side of the receptacle adjacent the impression cylinder 130 and a spring 142'is rigidly secured to the stop 141 and arranged to support the opposite edges of the envelops each of which is positioned in the receptacle with the loose flap or part to be sealed to the body of the envelop downward. A shaft 143 is mounted in a suitable position below the receptacle and a pair of hook shaped fingers" 144 are rigidly secured 'to' the shaft near each edge of the receptacle Sojtliirt; whenthe shaft is oscillated the extremity of the fingers 144 may be brought upward whicljrif the shaft'is turned in the opposite direction the fingers will enter between the flap ofthe envelop and the body portion drawing the forward edge of the envelop downward sufficiently to pass the lower edge of the wall of the receptacle 140, thence carrying the envelop out of thereceptacle and delivering the same between a a suitably and toward the cylinder 130 after formed 1'0l ler 145 and a plurality of belts 146. A semi-cylindrical casing 147 extends from the lower edge of the receptacle 140 into position to direct each envelop between the feed roller and belts. The belts 146 extend between suitable pulleys 148 and 149 mounted upon the shafts 150 and 151 respectively. A bar 152 is rigidly mounted upon the frame 1 and extends transversely of the belts in close proximity to and beneath the upper portion.

A strip 153 is rigidly secured to the bar 152 preferably at the outer edge of each of the outer belts 146 and extends toward the impression cylinder 130, a second bar 154 is secured to the frame and extends substantially parallel to and immediately above 'the bar 152. A resilient finger 155 is rigidly attached to the bar 154 for each strip 153, the fingers 155 are formed to coiiperate with the strips 153 and serve as a resilient stop to engage each envelop as it is delivered by the belts and hold the envelop in suitable position to be engaged by the grippers 137. Suitable means are provided for oscillating the shaft 143 and for rotating the shafts 150 and 151. In the form shown the arm 90 is provided with a segment 156 arranged to cooperate with a pinion 157 upon the end of the shaft 143 so that as the arm 90 is oscillated by the bar 88 the fingers 144 will be operated as hereinbefore described.

A rigid stud 160 is mounted upon the frame 1 and a pinion 161 of suitable size to mesh with the gear 139 is mounted upon the stud 160. A pulley 162 is also mounted upon the stud 160 and rigidly secured to the pinion 161. The ulley 162 is connected by a suitable belt 162 or equivalent means to a pulley 162 rigidly mounted upon the shaft 150, a pinion 163' is also rigidly secured to the shaft 150 and arranged to mesh with a pinion 164 rigidly connected to the roller 145. A second belt pulley 165 is also mounted upon the shaft 150 and a belt extends from the pulley 165 to a pulley 166 rigidly connected to a roller 167 near the lower end of the receptacle 140. A pair of arms 170 are also loosely mounted upon the shaft 171 of the rollers 145. The free ends of the arms 170 are adapted to coiiperate with the impression surface of the cylinder 130 to remove the envelop from the cylinder, the arms 170 are preferably connected by a bar 172 having a part 173 extending past the end of the cylinder 130.

A roller 174 is mounted near the free end of the part 173 and adapted to coiiperate with a cam 175'rigidly mounted near the end of the cylinder 130. The several parts are so proportioned and arranged that at each rotation of the cylinder 130 the arms 170 will be brought in close contact with the impression surface 131 and lift the envelop from the impression surface, the arms are preferably raised sufficiently as each envelop leaves the cylinder to bring the envelop into contact with the roller 167 which thus mechanically drives the envelops along the arms toward the roller 14:5 and out through the opening 176 in the casing 117.

Any suitable means may be provided for inking that portion only of the form to be printed upon the envelop. In the form shown, a shaft 177 is rotatably mounted u on the frame 1 and provided with an arm 1 7 rigidly attached thereto with an inkin roller 177 suitably mounted at its free en so positioned and arranged that the shaft 177 may be partially rotated to bring the roller 177 into contact with the type faces upon the carrier 9 temporarily in the form. The roller 177 is arranged when not in contact with the form to rest upon an ink spreading roll 178' of an ink font 178, the roller 178' is operated by a belt or other suitable means 178 from the shaft 151. An arm 177 is also rigidly attached to the shaft 177 with its free end en aging the free end of a lever 179 pivotall y attached to the frame 1 as at 179 and having a lateral projection 179 with a roller 179 at its free end adapted to periodically cooperate with a cam face 179 upon the end of the bed 2. The several parts are so arranged that at each rotation of the bed the roller 177 is moved into contact with that portion of the form upon thecarrier 9 and no more. A shield 179* is rigidly attached to the frame 1 to prevent the envelops attached to the cylinder from contacting with any part of the inking mechanism. Suitable means may also be provided for printing a signature upon each letter as it passes through the machine. As shown, a lever 195 is pivotally mounted upon the frame 1 as at 196 and provided with a suitable stamp 197 rotatably mounted upon one end beneath the impression cylinder 40. A roller 198 is provided at the opposite end of the lever adapted to periodically engage a cam face 199 upon the end of the bed 2 to move the st amp into contact with the sheet upon the impression cylinder, An ink pad 200 is rigidly secured to the frame in position to normally support the stamp 197, and a roller 201 is rigidly connected to the stamp so that when the stamp, which is so weighted that its face rests upon the ink pad 200 and isso directed away from the paper, approaches the paper the roller 201 will first engage the paper and the movement of the (y inder will thereby turn the stamp over having its face in contact with the paper at the desired point.

Any suita le means may be provided for driving our improved device. In the form shown a shaft 180 is mounted in a suitable bearing 181 upon the frame 1, a belt pulley 182 is rigidly secured to the outer end of the shaft 180, a pinion 183 is rigidly secured to the opposite end and arranged to mesh with a gear 184 loosely mounted upon a stud 185 rigidly secured to the frame 1. A pinion 186 is rigidly secured to the gear 18-1 and arranged to mesh with the gear 61. In operation the several carriers 9 are placed in the magazine 14, the desired form is secured in position upon the bed 2, paper is placed in the receptacle 66 and envelops in the receptacle 110. As soon as the mechanism is Started the head 8 will remove a carrier from the magazine 14 and print the form with the matter upon that particular car-' rier upon a sheet of paper from the receptacle 66 after which the sheet will be directed by the guide 190 into the receptacle 191. The ribbon during the printing operation moving with the form and without disturbing its position upon the ribbon carrier, a further movement of the bed 2 brings the carrier 9 to the auxiliary inking mechanism which inks only the name of the party for whom the letter was intended and his address which is immediately impressed upon an envelop from the receptacle 140. During this operation the finger 111 has returned, engaged a second envelop and delivered it into the space between the rollers 145 and the belts 146 which immediately transfer it into position to be engaged by the rippers, in the meantime the printed enve op is removed from the impression cylinder and as the fingers 141 are retracted is shot down the arms 170 through the opening 176 into the receptacle 192. At the same time the carrier head 8 has operated to place the carrier 9 in the magazine 12 after which it moves forward and removes a second carrier from the magazine It and the printing operations above described are repeated, the movement of the bed and the several impression cylinders remaining substantially constant and uniform during the entire operation of the machine.

Having thus described our improvement it is obvious that various immaterial moditications may be made in our device without departing from, the spirit of our invention, hence we do not wish to be understood as limiting ourselves to the exact form or construction shown.
